Germany's Revised Grid Plan Leaves Renewable Investors Uncertain
The economy ministry softened its network package, but renewable lobbies say the revised plan still designates broad German areas off-limits for new green capacity.
The German energy and economy ministry published its revised grid congestion plan late on Friday (2026-07-17), easing parts of the original package but failing to prevent renewable lobbies from calling certain areas a "no-go" for green construction, Montel reported.6
Germany expanded its installed wind and solar capacity by 60% between 2020 and last year, reaching 210 GW, while transmission infrastructure failed to keep pace. The result was curtailment of roughly 4% of renewable output over the past two years, Montel reported. A grid plan that restricts where new capacity can be built risks entrenching that mismatch rather than resolving it.6
At least 32 GW of wind and solar projects currently in development could be disrupted under the plan, a study by think tank Enervis for advocacy group Green Planet Energy found. That pipeline represents roughly EUR 45bn in potential investment.4
Industry groups told Montel in May (2026-05-21) that the original draft shifted investment risk heavily onto renewable developers rather than distributing it across the system. The softened version has not addressed that concern. "Uncertainty" was the word lobbies reached for after Friday's (2026-07-17) release.1,6
The bottleneck problem long predates the current plan. TenneT, Germany's largest transmission system operator, has committed to spending €200bn on grid infrastructure by 2034, according to The Economist. Yet the ministry's new package addresses where capacity can be built, not how fast the grid itself expands. That distinction matters for developers deciding now where to site the next wave of projects.3
German front-month power was trading at €132.45/MWh on Friday (2026-07-24), reflecting tight summer supply. Higher power prices make renewables more economically attractive in theory. They do not resolve questions of grid access that the plan has chosen to address through geographic restriction rather than accelerated network build.6
Spain-based Fotowatio Renewable Ventures secured grid capacity for 2.3 GW of planned German photovoltaic, battery storage and hybrid projects in June (2026-06-18), a sign that some developers were still pressing ahead before the revised plan's release. That allocation predates the zoning constraints that lobbies say will deter future commitments.5
The government's position appears to be that easing some geographic restrictions is an improvement on the original. Lobby groups disagree on the degree of improvement. Both positions can coexist: the plan is better than it was, and still likely to disrupt a large slice of the development pipeline according to the Enervis study.6,1,4
Experts told Montel that prioritising large-scale solar over rooftop installations, without expanding the grid simultaneously, already carries risks for Germany's renewable targets. The grid package as drafted does not obviously change that calculus. With Germany already receiving applications for an estimated 500 GW-worth of battery storage projects — more than 20 times current installed capacity, according to The Economist — geographic restrictions layered onto a first-come, first-served connection system add a further complication for developers queuing for access.2,3
The 32 GW at risk covers projects actively in development; actual cancellations will take months to confirm. Lobby groups have not specified which zones will be designated restricted, and the ministry may yet issue clarifying guidance. Until then, developers with pipeline in affected areas face a planning environment that has just acquired a new source of delay.4,6
